One organism’s trash is another organism’s treasure. Our cellular wastes, carbon dioxide and water, nourish plants, which with added energy from sunlight produce the oxygen and sugars that we need to survive. At microscopic scales, these cycles of waste and food can get much more complicated, with many species of microbes working together to survive…

Evolution connects all living things on earth, from the arsenic tolerant bacteria in the news this week to the human scientists and bloggers chatting about it. Eyes are intricately complex structures made up of many many cells, but even single-celled microbes can sense and respond to light through the function of proteins that share evolutionary…

An incredible (if unscientific) look at the history of life: The video has been around for a few months and has a gajillion hits so sorry if I’m late to the party, I just had to share! By Blu, via Bio Fiction

Life transforms environments, creating ecosystems where there was once only rocks. The evolution of photosynthetic bacteria billions of years ago created the atmosphere we have today, paving the way for the evolution of larger, oxygen-breathing organisms. We humans obviously transform our environment in countless ways, but can we also engineer barren environments to be hospitable…

I have a very weak constitution. It doesn’t take much time on a moving vehicle of any type to make be barf, and I’ve hurled all over gorgeous coastal areas in tourist destinations around the world. There was that one time in Italy, snapping photos of the incredible shoreline caves (now dubbed barf grottos), that…

I love this quote from the XKCD blog: The role of gender in society is the most complicated thing I’ve ever spent a lot of time learning about, and I’ve spent a lot of time learning about quantum mechanics. Many scientists try very hard to de-emphasize this complexity, trying to reduce “human nature” down to…

Are aliens little green men of unpredictable motives? Horrible insect-like face-hugging, chest-exploding monsters? Are they super-smart, super-slimy, super-fishy, body-cavity-probing, disc-flying creatures, searching for planets to colonize and people to destroy as Stephen Hawking warned, or are they something much more mundane? Could there be alien life already on earth, too microscopic, too different to notice?…

There have been a lot of great Darwin themed things popping up in the past few months in celebration of the 150th anniversary of On the Origin of Species, but none as avant garde and awesome as “Tomorrow, in a year“, an electro-opera based on the life and work of Charles Darwin by The Knife,…

I am kind of obsessed with symbiosis and the idea that cooperation between different species can be a driver of evolutionary change. I learned about these symbiotic green sea slugs a while back from a colleague whose mom is a zoologist who studies the evolution of symbiosis between invertebrates and photosynthetic microorganisms. A review article…
